Abstract
A touch sensor includes a substrate layer, sensing electrodes on the substrate layer, and optical compensation patterns. The sensing electrodes include electrode lines therein which extend in different directions to cross each other. The sensing electrodes are defined by separation regions at which portions of the electrode lines are cut. The optical compensation patterns are disposed at a different level or a different plane from that of the sensing electrodes. The optical compensation pattern at least partially fills the separation regions in a planar view. Optical properties of the touch sensor are improved by the optical compensation pattern, and visibility of electrodes is prevented.
